限制每小时的电子邮件数量 joomla
我有一个 Joomla 设置为使用外部 SMTP 发送邮件。 SMTP 服务器不受我的控制，无法对其进行任何更改。
现在我看到很多帐户激活失败的邮件以及用户抱怨他们没有收到任何电子邮件。从 SMTP 服务器管理员的响应来看，这是由于广播电子邮件太多。示例：
<[email protected]>: delivery temporarily suspended: Host or domain name
not found. Name service error for name=gmail.com type=A: Host not found,
try again
<[email protected]>: connect to
yahoo-wildcard.a05.yahoodns.net[98.137.132.14]: Operation timed out
我的 Joomla 直接连接到 SMTP 服务器，所以现在我需要一种方法来限制每次发送的电子邮件数量，以免淹没收件人服务器（Google、Yahoo 等）。
我一直在网上搜索，但答案不太明确，由于这是一个生产网站，因此非常感谢快速回答。
I have a Joomla set up to use an external SMTP to send mails. The SMTP server is not under my control and no changes can be made to it.
Now I am seeing a lot of failed mails for account activation as well from user's complaint they do not receive any email. From the response of the admin of the SMTP server it is due to too many broadcast email. Example:
<[email protected]>: delivery temporarily suspended: Host or domain name
not found. Name service error for name=gmail.com type=A: Host not found,
try again
<[email protected]>: connect to
yahoo-wildcard.a05.yahoodns.net[98.137.132.14]: Operation timed out
My Joomla is connecting directly to the SMTP server so now I need a method to limit the number of emails sent each time to not flood the recipient server (Google, Yahoo, etc).
I've been scouring the net with less than clear answer and since this is a production website, a quick answer is greatly appreciated.

这是“服务器上”电子邮件营销的常见问题，这就是为什么我通常建议使用站外电子邮件平台，例如 mailchimp 或 Constantcontact。有一系列 Joomla 模块可以为您处理集成。
或者，您可以查看处理大量电子邮件的 Joomla 组件，其中大多数也支持电子邮件的“批处理”，但是研究工作是在一个小时结束时确定特定 ISP 将允许多少电子邮件通过。
速率还会受到其他因素的影响，例如您的电子邮件的实际内容以及它与垃圾邮件的兼容性如何，您是否使用真实姓名作为发件人，您发送的电子邮件地址是否存在，SPF记录，基本上影响垃圾邮件评级的所有内容。
综上所述，这就是为什么我建议把它交到场外，有些平台甚至免费做一定量的电子邮件。
this is a common problem with email marketing "on server", which is why I generally recommend to use off-site email platforms such as mailchimp or constantcontact instead. There are a range of Joomla modules that handle the integration for you.
Alternatively, you could look at Joomla components that handle mass email, most of these support "batching" of emails as well, however then the research work is on hour end of how much specific ISPs will let through.
The rate will also be affected by other factors, for example the actual content of your email and how spam compatible it is, if you are using a real name as a sender, if the email address you are sending of exists, SPF record, basically everything that affects a spam rating.
In summary, this is why I recommend to hand it off-site, some platforms even do a certain amount of emails for free.
